Thanks Tom and Eric, finally resolved this, it ended up being a power supply issue. The unit we used to typically run it on the bench seemingly browned out somewhere in the flashing procedure.

Thank you very much for your reply!
We bought the USB C adapter from Flir and followed your guide to enable MIPI. Now it works and I can get the video from the Boson over MIPI.
Thanks for your help!
